左冠状动脉异常起源于肺动脉(anomalous origin of left coronary artery from the pulmonary artery,ALCAPA)又称BlandWhite-Garland综合征~([1-3]),是一种罕见的先天性心脏畸形,在新生儿中的发病率为1/30万,占先天性心脏病的0.24%~0.46%。其临床表现、心电图、超声心动图、胸片等,尤其是心电图出现Ⅰ、a VL、V5、V6导联病理性Q波,V5、V6 ST段抬高的表现具有相对特异性~([4,5])。对于基层临床儿科医生来说,认识到这些特点可以提高该病的诊断率。本科诊断1例左冠状动脉异常起源于肺动脉,现报告如下。
Left anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA), also known as BlandWhite-Garland syndrome ~ ([1-3]), is a rare congenital heart disease, in neonates In the incidence of 1/30000, accounting for 0.24% ~ 0.46% of congenital heart disease.
